Most long wavelength or Rayleigh scattering processes can be described in terms of volume effects: the scattered fields for single scattering are proportional to the volume of the scattered and to the anomalous excess or deficiency in the physical properties causing the scattering. Rayleigh scattering has, by now, been studied with sufficient detail for wave propagation in a wide number of modes (elastic, acoustic, electromagnetic, etc.) so that it is well understood.https://authors.library.caltech.eduhttps://authors.library.caltech.edu/records/7k84g-s6a64Diffraction of Scalar Elastic Waves by a Finite Crack

In an earlier paper, we have presented the long-wavelength solution to the problem of the diffraction of scalar waves by a two-dimensional strip. The boundary conditions in the above solution were such that the strip was clamped. A more important problem for practical reasons is that of the diffraction by a strip with weak boundary conditions, that is, conditions for which the normal stresses vanish.https://authors.library.caltech.eduhttps://authors.library.caltech.edu/records/pp4rq-wr303Diffraction of Vector Elastic Waves by a Clamped Finite Strip

In earlier papers we have considered the problems of the scattering of elastic waves by a two-dimensional crack with either clamped or weak boundary conditions. The crack is considered to occupy the region y = 0, -1 < x < 1, - ∞ < z < ∞ in an otherwise infinite homogeneous elastic medium. In order to introduce the method of calculation, the scalar cases, that is, those in which the elastic displacement vector points in the z-direction, have been considered for the two types of boundary conditions.https://authors.library.caltech.eduhttps://authors.library.caltech.edu/records/efph1-jw335Diffraction of Vector Elastic Waves by a Finite Crack

The problem of the diffraction of obliquely incident scalar waves by finite slits and strips with various boundary conditions has been considered previously. Reference may be made to the work of other authors on the diffraction of scalar waves by finite slits. The problem of the diffraction of obliquely incident vector elastic waves by a clamped finite strip has also been treated.https://authors.library.caltech.eduhttps://authors.library.caltech.edu/records/p9n84-8bz14
